Typically, the disruption is so great, that the exercise must be essentially reset without the cyber intrusion to allow enough operational capability to proceed. These stark demonstrations contribute to the Task Force’s assertion that the functioning of DoD’s systems is not assured in the presence of even a modestly aggressive cyber-attack."
